Changed spaces_access in spaces_og to correctly handle non-spaces enabled pages, adjusted spaces_init to first confirm url loading is in correct space. With much help from Hefox

Made declaration of spaces_og_handler_field_og_group_nids::pre_render() compatible with that of og_views_handler_field_og_group_nids::pre_render()

Issue #825048 by hefox: When performing a features_access the check is using the current space for the varible_get, where a space can be specified

Fixed a Spaces Views Access Permission botch that allowed access to a view page to an unprivileged user

Reworking Spaces OG test to use xpaths and not regex for form testing and only do one thing at a time.

Fix wrong argument passed to features_get_component_map which resulted in the strings from views not getting picked up by the spaces custom text module

Adding an implementation of json_decode to spaces instead of relying on context for it when the php is less than  5.2.
